DNA has the base thymine whilst RNA has the base uracil.


This is the main difference between DNA and RNA. Also, RNA is used in DNA replication - mRNA moves from the nucleus to the cytoplasm and tRNA is involved in the synthesis of new DNA.

The other main difference is that Ribose uses a ribose sugar, whereas DNA is actually called 2`-deoxyribonucleic acid, and does not have an OH group at the 2nd carbon on the ribose sugar. This is important for the stability (lessened reactivity) of DNA.
